reeds or straws that are used to build a roof

Thatch is a natural material made from dried plants like straw, reeds, or grass, used to cover roofs. These plant materials are tightly layered to create a roof that provides protection from rain and helps insulate the building. Thatch is a traditional roofing material often found in rural areas or older buildings and is valued for its natural look and ability to keep homes cool in hot weather and warm in cold weather.
